Research has shown that TMCO1-AS1, a newly identified lncRNA with aberrant expression in hepatocellular carcinoma, correlates positively with α-fetoprotein (AFP) levels, tumor stage, and cellular differentiation grade, acting as a predictive biomarker for both overall survival (OS) and recurrence-free survival (RFS) [46]. This evidence concerns the gene TMCO1 and neoplasm.
